Nicole Richie Is Calm, Cool & Collected at Traffic School

Nicole Richie sipped on her cup of coffee as she headed into traffic school today in Van Nuys, Calif. The starlet looked great for class, wearing a summer-ready dress. Nicole is also going green — environmentally conscious with her eco-friendly, reusable travel cup! We didn’t know Nicole still had to go to traffic school after her 2007 driving arrest — but it’s good to see she takes driving seriously.

Nicole is definitely on the straight and narrow.

She is a great mom to children Harlow and Sparrow, and is happily planning her wedding to musician Joel Madden!
